Thermal barrier mixtures and uses thereof

Abstract

Thermal barrier mixtures and method of making the thermal barrier mixtures are described herein. The thermal barrier mixtures may be used to make thermal barrier coatings. Thermal barrier mixture may include halloysite and one or more silicon compounds.

What is claimed is: 
     
       1. A thermal barrier coating comprising halloysite nanotubes, silicon carbide, and ceramic microspheres. 
     
     
       2. The thermal barrier mixture of  claim 1 , further comprising one or more phosphate esters. 
     
     
       3. A thermal barrier coating comprising one or more polymeric compounds, halloysite nanotubes, silicon carbide, and ceramic microspheres, wherein a total amount of halloysite and silicon carbide is between 0.1 and 50% based on the total weight of the one or more polymeric compounds. 
     
     
       4. The thermal barrier coating composition of  claim 3 , wherein at least one of the polymeric compounds is selected from the group consisting of polyurethanes, epoxies, polyester, polysiloxanes, and latex. 
     
     
       5. The thermal barrier coating of  claim 3 , further comprising one or more phosphate esters. 
     
     
       6. A method of making a protective coating for a substrate, comprising applying a thermal barrier coating to one or more substrates, wherein the thermal barrier coating comprises one or more polymeric compounds, halloysite nanotubes, ceramic microspheres, and silicon carbide, wherein a total amount of halloysite and silicon carbide is between 0.1 and 50% based on the total weight of the one or more polymeric compounds. 
     
     
       7. The method of  claim 6 , wherein the substrate is selected from steel, plastic, wood, or mixtures thereof.
